Total number of students = 375
Boys = 195
So, girls = 375 - 195 = 180
⅗ of the boys walk to school
= ⅗ × number of boys
= ⅗ × 195
= 117 boys
⅔ of the girls walk to school
= ⅔ × number of girls
= ⅔ × 180
= 120 girls
Total number of pupils who walk to school
= number of boys who walk to school + number of girls who walk to school
= 117 + 120
= 237 pupils
